Question

(7x) - (6y) multiply by 3z​

Answer 1

Given: (7x) - (6y) multiply by 3z.

To Find: The answer to the multiplication.

Solution:

Putting (7x) - (6y) in brackets so that we can multiply it by 3z,

3z $\times$ { (7x) - (6y) }

Removing the first brackets, we get,

3z $\times$ { 7x - 6y}

= 3z $\times$ 7x - 3z $\times$ 6y

= 21xz - 18yz

Answer: 21xz - 18yz

Note

• We need to multiply both the variables given in question by 3z to find the answer.

• The numbers get multiplied. However, the variables are placed side by side as they are not the same variable.

Answer 2

Here we have to find out the answer of the multiplication.

(7x) - (6y) multiply by 3z.

= { (7x) - (6y) } × 3z

=3z { 7x - 6y}

= [( 3z ×7x) -( 3z ×6y)]

=$( 21xz - 18yz)$

Answer :-Multiplying  (7x) - (6y)  by 3z​  we get ( 21xz - 18yz).
